This invention relates to improvements in loose leaf supporting arrangements, and "re-.-

fers more particularly to loose leaf binders whereinparallel tongues are provided-subi stantially centrally Vof their f width .which usually extend, the full-heightof the binder and between which leaves are to be held.

It is an object ofthe invention tov provide a loose leaf supportingarrangement wherein binding posts having annular grooves adja-l cent their outerextremities extend:` laterally from one of zthetongues andare adaptedto project v through,` apertures in .the other-y tongue,` and wherein pivotal locking meinA bers oii the said other tonguehold the bind-1` ing posts relative to the latter so that leaves through which the posts `pass areh'eld'betweenthe tongues.- fj Other objects of the invention` are nto provide such a loose leaf V `s'uppc` rtir ig "arrangement, wherein the pivotal locking'members are so constructed thatv they reinforce adjacent portions ofthe tongue on whichthey are mounted and` through which the binding posts pass, and wherein the various 'parts are' simple to manufacture, assemble and-use. l With these and other objects and advantages in view' which will become apparent as the specication proceeds, the invention `is hereinafter more fully described with the aid of the accompanying drawings, in which Figure 1 illustrates a perspective view of a loose lea-f binder equipped with the invention. i r

Figure 2 is an enlarged plan view ofa portion of a binder showing the leaf-supporting* arrangement. f Y

Figure 3 is an enlarged` side view of the supporting arrangement without a binder,

and

Figure4 shows an enlarged cross-sectional view of a portion of `a binder with leaves therein and the supporting arrangement; the latter being shown as a section on the `line 4-4 of Figure 3.

Referring tothe drawings, 1 designatesl a conventional binder Vhaving two parallel tongues 2 and 3 positioned substantiallycem trally thereof and extending inwardly for the full height ofthe binder. Between. these` extremities. i

The binding posts 5 may bel of anydesired tongues leaves, 4 are held.` Secured tothe tongue. 2 are a plurality of binding posts 5` which projecttowards the tongue 3 and are Y adapted to pass through apertures 6 inthe latter. `The posts 5 have annular grooves 7 formed4 around them construction and may be secured to the tongue V2 in any desired manner. In the present in` stance Y they consist of tubular internally threaded members 8 `which extend through openings formed in the tongue 2 and have in-l tegral flanges 10 intermediatelyof their; length which bear against the inner side of the tongue 2. These members 8 are held in position by their expandedends 8a `which bearagainst washers 11 placed around their ends. vThese washers 11 rest also against the outer side of the tongue 2. Inthreaded engagement with the members `8 are vextensions 12 around which the" annular grooves 7 `are formed adjacent their!v outer Y extremities.

- These extensions may of course be adjusted so l that their grooves 7 are positioned at various distances from the tongue 2to adjust the spacj ing between the tongues?. andl `3 to suit the number of leaves 4 held between them.

Locking members 14, substantially `U- sh'aped in ci'ossvsection, are pivotally mount-` `ed on the tongue 3. adjacent the apertures 6 by ri-vets 15. Theseflockingmembers areso constructed and arranged that their folded `intermediate portions 14a may lie adjacent portions of the outer margin of the tongue 3 and parallel with theqlatter. Inthe sides of the members 14 opposed marginal recesses 16 adjacent their outer and 16a are formed.V The recesses 16 are of such size that .their margins may engage the binding posts grooves 7 andy hold them against.` `axial movement; these recesses are'v formed' inthe outer sidesofgthemembers 14. The recesses 16a formed inthe inner sides of'` the members 14 are larger than the recesses 1 `16 :so that whenrthe latter `engage the grooves he recesses 16e partlyencircle butlieclear i of the binding postsf.-` A c' A-At the pivoted `endsofthemembers 14 Y Vtheir ,interinediate folded portions j are out, away as shown at 14o so `as to permitthememlma #laterally therefrom, the other tongue havingV bers to be turned from their downturned position shown at A in Figure 1 into the upturned position shown at B. In order to facilitate the turning of the members 14, their outer sides are cut away as shown at 17 at their ends remote from the rivets 15, so that finger holds are afforded whichlie substantially parallel with their intermediate folded portions 14a and adjacent thereto. Y

The operation of the device is, of course, as follows: When it is desired to open the leafsupporting arrangement the members 14 are moved pivotally from their position shown at A to that shown at, B when the binding posts are free to be withdrawn from the apertures 6 through the tongue-3. The leaves 4 are thenV n for the sides of the recesses to be moved free free to be removed from the binding posts.

f From the foregoing it will be clearly seen that I have not only devised a simple and eilicient method of supporting leaves in binders andvof holding binding posts againstmovement relative to a tongue through apertures in which the said posts are intended to remain, but that the tongue adjacent its apertures is strengthened by the locking members,

and also that on account of the sides of the said members lying adjacent both sides of the l -tions-may be made thereto provided the said alterations and modifications fall within'the scope of the appended claims. f Y

What Iclaim as my invention and'desire to secure by Letters Patent is:

1. In an arrangement of the character described, the combination of a binder cover having two opposed and parallel tongues between which leaves are to be mounted, binding posts secured to one tongue and extending apertures therethrough through which the binding posts may pass, said posts having an nular` groves formed around them, and lockingcmembers pivoted on said other tongue, said members being folded so asto be substantially U-shaped in section so that their intermediate folded portions extend over the outer margin of said other tongue and their sides are disposed on opposite sides of said other tongue, said members having marginal recesses formed 'therein so that the sides of v the latter may engage said annular grooves 5 and lhold the binding posts against movement. y f

scribed, the combination of a binder cover having two opposed andparallel tongues be- Y tween which leaves are to be mounted, bindlocking members pivotally mounted on said other tongue, said members being folded so as to be substantially U-shaped in section so that their intermediate folded portions extend over the outer margin of said other tongue and the sides of each member are disposed on opposite sides of said other tongue, the sides of said members having marginal recesses formed therein to engage said annular grooves and the intermediate folded member portions terminating adjacent the pivoted ends of the members so that the latter may be turned relative to said other tongue of the annular grooves lin the binding posts.

.3. In an arrangement of the character described, the combination of a binder cover having two opposed and parallel tongues be-v tween which leaves are to be mounted, binding posts secured to one tongue and extending laterally therefrom, the other tongue hav-4 'ingV apertures therethrough through which the binding posts may extend, said posts having annular grooves formed around them, andflocking members' pivotally mountedV on said other tongue, said members being folded so asto be substantially U-shaped in section so that their intermediate folded portions extend over the outer margin of said othertongue andthe sides of each member are disposed on opposite sides of said other tongue,

the sides of said members having marginal recesses formed therein to engage said annular grooves and finger holds providedl on said locking members by which the latter are intended vto be engaged when they are to be moved pivotally on said other tongues.

Ll. In combination a binder cover having two opposed tongues between which leaves are to be mounted, one of said tongues being apertured, a binder post extending from one tongue so that it may be passed through the apertured tongue, said vbinding post having an annular groovearound its outer extremity a rlocking member pivoted on the apertured tongue, said member being folded so as to be substantially U-shaped in section, said member lhaving opposed marginal recesses formed therein one of which may engage said groove, and the other recess partly encirclingY said post when the first-named recess 1s 1n Vengagement with said groove.
